Windows XP Service Pack 2 will be sent to manufacturing in August, a month later than expected. The product should be in customers’ hands later that month. This is the second time that Microsoft has delayed SP2, which was originally expected in June. Last month, a number of Windows enthusiast Web sites reported that Microsoft had run into compatibility problems between SP2 and other software. Work on SP2 required the company to pull engineers off of Longhorn, the next major release of Windows, which is expected in 2006.
